Only the cartoon for me. But, it had to be anyways since I don't read much comics to begin with.

I didn't used to either, but it's given me a much richer appreciation for the love, care, references, and little quirks of the films that would have completely flown over my head otherwise.

You should totally dive in and check out the major Batman books that you think might interest you. For me, it's kind of a romantic experience - but then again, there's also a lot of disappointment to be found too. lol
